Summary

This study tests if whole-body light therapy (photobiomodulation) can safely improve movement and thinking in people with Parkinson's disease. Fifteen adults with mild to moderate Parkinson's will receive about 30 sessions over 10 weeks. Researchers will measure changes in motor skills, balance, and memory.
